poor rekmanship
Similar to bad sportsmanship. Poor Rekmanship is when you get 'rekt' or 'GG no re'd' but instead of accepting the defeat, you go off to complain and refuse to believe you got 'rekt'(IE being a bitch about it).
Person 1: Dude this is fucking bullshit!
Person 2: You just got rekt Mr. Mang
Person 1: Shut up! My team was shit and I was lagging!
Person 2: Your team was fine and bullshit you were lagging....That's poor rekmanship mate!
